WILLIAM SKAKEL, 0F AVON, SOUTH DAKOTA.

MANURE-LOADER.

Application filed December 4, 1912.

To all whom it may concern Be it known that I, WVILLIAM SKAKEL, of Avon,in Bonhomme county, in the State of South Dakota, have invented certainnew and useful Improvements in Manure-Loaders, and have described thesame in the following specification, illustrated by the accompanyingdrawings.

My invention relates in general to that class of loading apparatus andmanure loaders, in which a scraper, movable upon the ground and adaptedto gather quantities of manure or the like therefrom, is carried to andfrom a position of discharge at a suitable distance above the ground bymeans of a swinging frame pivoted to the ground or to a stationary baseby the sideof a wagon into which the contents of the scraper drop.

It relates in particular to those loaders of the specified class whichare constructed substantially as shown in Letters Patent of the UnitedStates No. 984,164t, which were issued to me for manure loaders February14, 1911.

It is the object of the invention to control, in loaders ol' this class,the tilting movement which is performed by the scraper in dischargingits contents; to render this movement of the scraper dependent upon thepivotal movement of the swinging frame by which the scraper is carriedto its dumping position; to prevent this movement of the scraper fromoccurring too soon, or before it has fully reached that position; topredetermine that position variably by adjustment; to return theswinging frame automatically to its lowered position, after the scraperhas dumped its load into the wagon; and in general to produce a superiorloader of the specified class. To accomplish these objects I incorporatein my improved loader of the specified class a dog for holding the ropewhich actuates the scraper, tripping mechanism for releasing the dog,means for adjusting the tripping mechanism, and a spring for retractingthe swinging frame.

The best manner in which I have contemplated applying the principles ofthe invention, is shown in said drawings.

In these Figure 1 is a side elevation of a manure loader which isconstructed in accordance with these principles and is positioned aswhen the scraper is discharging its contents. Fig. 2 is a side elevationof the same loader positioned as when the scraper Specification ofLetters Patent.

is being carried to its dumping position. Figs. 3 and 4; are details.

This illustrative loader comprises the scraper 1, having a transversesliding pivot 1, the bail 2 secured to the front of the scraper, thesheave 3 secured to the bail, the swinging frame t on which the scraperis adapted to be raised above a wagon, the legs 5 and the inclined track6, which are adapted to sustain the middle and the free end of theswinging frame above the ground, the base 7, which is anchored to theground by the side of a wagon by the corner stakes 8, the sheave 9secured to the free end of the swinging frame, and the operating rope,or

cable, 1.0, which is attached to the swinging frame, and runs in saidsheaves; all constructed and operated in the same general manner as thetypical loader of the specified class, namely, the loader described andshown in my said Patent No. 98%,164.

In the block of the sheave i) is pivoted the dog 1.1, which is adaptedto bite the rope or cable 10 and thereby to stop and hold the scraper 1by its bail 2 in the carrying position shown in Fig. 2. The attached endportion of the cable is preferably composed of metallic links, as shown,since they are readily engaged by the dog and not soon worn out byrepeated engagements. The mechanism for tripping the dog comprises theConnecting-rods 12, the bellcrank levers 13, the chain 17, the bolt 14,longitudinally slidable in its seat in the bracket- 15 on the base 7 bymeans of the adjusting nut 10. The coiled spring 18 for retracting theswinging frame, is similarly attached to the same bracket by the bolt1%) and the nut 20, whereby the drawing tension of the spring isadjusted.

The operation of the loader with my improvcments is as follows: Afterthe scraper has been loaded by drawing it forward on the ground, afterthe usual manner of such scrapers, it is still drawn forward by theoperating rope 10 connected thereto by the bail 2, and is thereby causedfirst to slide onto the ascending two-rail track (3 which is carried bythe swinging frame -11- standing on the ground on its legs 5. As thepull of the rope continues, the scraper, whose opposite ends slidercspectively on the rails of that track, travels up and along the latteruntil the sheave 3i meets and is stopped by the sheave 9 near the freeend of the swinging frame. Then, as the pull still continues,

that frame, together with the track 6, is swung pivotally from itsposition on the ground, through the intermediate position shown in Fig.2, to the extreme for-Ward position shown in Fig. 1. Thereby thescraper, riding upward and forward on and with the swinging track, iscarried in a gen. erally horizontal posture to a position above thewagon into which its contents are to be discharged by the pivotaltilting of the scraper to its inclined position shown in Fig, 1, In thisposture the scraper is held till the rope 10 is slackened and isreleased by the, dog ll, The tripping of the dog which holds the rope,is'tiniltl by the described bolt-and-nut adjustment of the trippingmechanism to occur at the instant, and notbefore the instant, when thescraper has r a he it desc i ed ex reme forwa d position, W hen the ropeis released by the l g, h sc aper, which is suPpQr ed on th track railsby its transverse sliding pivot 1 tips forward to the position shown'inFig. 1 drops its contents into the bed of the wagon below, and is thenpulled back by handor otherwise for another load. The'operating powerbeing released, this pulling "back of the scraper causes or permits the's winging frame to return to its original position supported on theground by the legs 5.

1 claim as my inventione 1. A loader of the specified class, comprisinga stationary base, a frame pivoted to the base and carrying an inclinedtrack, a scraper movable both on the ground and also on the track, anoperating cable engaging the scraper and the pivoted frame, a dog forengaging the cable, and adjustable automatic means for tripping the dog.

2. A loader of the specified class, comprising a scraper movable overthe ground,

sheaves, a dog for stopping and releasing the cable, and means forcontrolling the action of the dog by the position of the frame.

4. A loader of the specified class, comprising a scraper, a pivotedframe adapted to raise the scraper from the ground, a cable actuatingthe frame and the scraper, a dog to engage the cable, means for trippingthe dog, and a'spring acting upon the frame against the pull of thecable.

5 A manure loader of the specified class, comprising a scraper, a bailsecured to the scrape ga sheave secured to the bail, a pivvoted frameadapted to be raised above a wagon, legs or an inclined track supportingon en of t e ame above t e gro means for securing the other end of theframe at the sicleof a wagon, a sheave secured to the raised end of theframe, a cable running in the sheaves, means for controlling the runningof the cable, and means for V retracting the raised frame when the cableis released,

In testimony whereof I hereunto set my signature in the presen of t Witne WILLIAM SKAKEL. In the presence of W LLARD ED E A A LEY- G pies his pant may b obta ne o e cent ea h, i ad ssi the m i io e o i s, Washington,D. Q.
